Introduction

Product Upgradable Sounds Halo contains a new collection of presets designed for music composition Description in a wide variety of styles.These sounds are rich in harmonic texture and a perfect complement to the Z-plane ﬁlters. Halo contains three additional, user-upgradable sound SIMM sockets, allowing you to mix and match sound sets according to your needs. New sounds can be added as easily as plugging in a new 16MB or 32MB SIMM module. Each sound set has been meticulously crafted to be the ﬁnest of its kind. Samples are expertly matched across the keyboard and perfectly looped to create realistic instruments which form the exceptionally playable presets.

1024 Presets & more Halo contains 512 user presets and 512 factory ROM presets, but it can be expanded with literally thousands of ROM presets. (ROM presets are automatically added when sound SIMMs are installed. As an example, a 32 MB SIMM may contain up to 1024 ROM presets.) Halo’s Sound Navigator makes it easy to ﬁnd the exact sound you want. It’s powerful, yet simple to use.

Velocity & Pressure Sensitive Keyboard The ﬁve-octave, velocity sensitive keyboard with aftertouch allows you to perform live or record via MIDI into an external computer/sequencer. The keyboard action is extremely responsive, capturing all the subtle nuances of your performance.

Multi-Function Controllers Multi-function buttons allow you to trigger arpeggiators and notes internally or on any of your other MIDI devices. They can act as preset select buttons or Beats Mute or MIDI Trigger buttons (latched or unlatched). Four real-time controller knobs are also multi-function controls. These knobs make it a snap to edit and modify internal preset parameters. The controllers are fully programmable and can control internal preset or other MIDI equipment. They can also be programmed to adjust multiple internal parameters at once, allowing complex levels of control. For example, a single knob can simultaneously turn up ﬁlter cutoff, while detuning one

Introduction Product Description

sample, and adjusting the release time of the volume envelope. Virtually every synth parameter in the Halo is controllable using the real-time knobs or by any internal or external control source.

SuperBeats Beats Mode is a whole new way to create dynamic, original music. With Beats, you trigger, latch and unlatch synced loops and grooves from the sixteen trigger keys. Simply select a bts: preset and go. Then use Halo’s perfomance controls to alter and mutate the rhythm or the sound itself.

Multi-Channel Arpeggiators Halo’s Rhythmic Pattern Generator/Arpeggiator can play up to 16 synchronized arpeggiator patterns at once using a different sound for each! Patterns can be edited using pattern ﬂow commands such as: delay for 2 bars, play for 4 bars, hold for 2 beats and repeat. You can program or download 100 user patterns in addition to the 200 factory patterns.

Ultra Powerful Synthesizer The extremely flexible yet easy to use synthesizer makes it easy to build sounds of any kind. Up to 4 four layers can be switched or crossfaded using key position, velocity, real-time controllers or any modulation source. 64 voice polyphony ensures that you can play and sequence the most complex material. Halo also contains 50 different 2nd to 12th order resonant & modeling filters which are used to shape and modify over 1200 waveforms contained in 32 megabytes (MB) of ROM. Sixty-four modulation sources include three multistage envelopes and two LFOs per layer, as well as full MIDI control over virtually every parameter. The digital patch bay, with 24 cords per layer, (and 12 more cords per preset) lets you connect modulation sources to 64 destinations in any imaginable way. The patch bay also contains a set of arithmetic modifiers, allowing you to create complex synthesis models. Synth parameters as well as arpeggiator and BEAT tempos can be controlled from Halo’s internal clock (or an external MIDI clock). Up to 8 LFOs and 12 envelopes can be perfectly synchronized at different rates.

24-bit Effects Once you have created your preset, you can add richness to your sound using Halo’s 24-bit stereo effects. You can choose a different effects setup for each preset from over 60 algorithms. Halo’s effects section is actually two separate effects processors with control over each wet/dry mix level on four effects sends. Effects Processor “A” contains primarily ambiance algorithms like reverb and delays, while effects processor “B” contains primarily spectral algorithms such as chorus, flange, phase, distortion, and delay. Effects can be linked to each preset or used globally for increased flexibility. Other features include multiple solo, voice assignment and performance modes for expressive control, 12 user-definable alternate tunings, and, of course, an extensive MIDI implementation.

Therefore, the Sub 1 jacks can serve as effect sends and returns in order to further process selected instruments and then return them to the main mix.

You can use the Sub 1 jacks as send/returns in order to further process selected Halo presets without using the effects bus on the mixing board.

Basic Operations

The Halo front panel contains an LCD screen, 35 buttons, and 4 real-time controller knobs. Functions are grouped logically and the controls are arranged for ease of use.

Power Switch The power switch is located on the rear panel next to the AC power receptacle.

Volume Control This control is the master volume control for all audio outputs. The Volume Control does not affect any editing or user interface operations. The front panel volume control is a digital attenuator. For maximum dynamic range, turn this knob all the way up and control the volume from your mixer or ampliﬁer.

Channel +/- Buttons These very handy buttons, located to the left of the LCD, serve as a shortcut to increment or decrement the MIDI Channel (in Preset mode), Layer (in Preset Edit mode) or Step Numbers (in Arpeggiator Edit mode).

Data Entry Control The data entry control is a stepped, variable control switch used to change parameter values. The wheel increments or decrements the current value

one unit with each click. This control incorporates acceleration, which advances the value faster if the data entry control is turned quickly.

Cursor Buttons These buttons, located just above the Data Entry Control, move the cursor to the next parameter on the display. (The cursor is a little ﬂashing line underneath one of the parameters in the display.) Press either cursor button until the cursor is underneath the desired parameter. The cursor buttons have an auto-repeat feature which advances the cursor when the button is held continuously.

The cursor can be moved bidirectionally using the data entry control while either cursor select button is held down (for example, press and hold the right cursor button and turn the data entry control).

Pitch & Mod Wheels These two controls, located to the right of the keyboard, are performance expression controls. The left “Pitch Wheel”, is spring-loaded and is normally used to bend the pitch up and down while playing. The center position is off. The pitch bend range is set using the “Pitch Bend Range” parameter in the Global menu (page 84).

The right “Mod Wheel” is programmed to add vibrato in most of the factory presets. Like all the controllers in Halo, the Mod Wheel can be programmed to control any synthesizer parameter. See PatchCords on page 102 and page 157 for more information.

Save/Copy Button The Save/Copy button is used to save changes to a preset, copy data between presets, randomize presets and to move other types of data. Selected groups of parameters, such as PatchCord settings, can be copied between Presets and/or between Layers using this menu. The menu is context-sensitive and will start at the appropriate save screen. See Save/ Copy on page 187 for more information.

The LED in the button illuminates to indicate that you are in the Save/ Copy menu. The LED also illuminates when any preset parameter has been changed in the Preset Edit menu (or if the front panel knobs have been moved with Quick-Edit mode enabled).

Preset Edit Button The Preset Edit menu allows you to create and edit presets. An illuminated LED in the button indicates that you are in Preset Edit mode. For more information about the Preset Edit menu, see page 129.

Home/Enter Button The Home/Enter button is dual purpose. In general, this button acts as the “Home” button. For example, when in an Edit menu, this button snaps the cursor to the page name field of the current screen. When viewing the Preset Select screen, this button snaps the cursor to the preset number field. The flashing green LED of the Home/Enter button indicates that pressing the button will initiate a particular operation.

Real-time The Real-time Controller Knobs serve dual purposes. Knobs Preset Quick Edit (page 79) can be enabled to use the knobs for editing in the Preset Edit Controller menu.

The Save/Copy button LED ﬂashes to remind you that the preset has been edited. “Quick-Edits” made to a preset are lost if you select another preset before saving them.

The three rows of knobs always control the preset on the basic MIDI channel (the channel showing on the preset select screen), when the control switch is set to Quick Edit. The labels (Filter Cutoff, Filter Q, Filter Attack, Filter Decay, etc.) printed on these rows show how the factory ROM presets are programmed to respond. (The controls may not exactly conform to the front panel labels depending on the preset.) You can change the way a preset responds to MIDI A-L messages from the Preset Edit menu (PatchCords). The knobs only generate a message when you move a knob to a new value. The current value jumps to the new value.

To Quick-Edit a Preset: 1. Select Quick Edit mode using the Controller Function Select button. 2. Use the Control Knobs to change the sound of the current preset as desired. 3. Press the Save/Copy button. You may have to turn the data entry control so that the display reads, “Save PRESET to.” 4. Press the right cursor button to select the bottom row. 5.

40 ENSONIQ Basic Operations Multisetups

Multisetups A Multisetup is a group of parameters that you might associate with a particular performance setup or song. It is like a “snapshot” of the current conﬁguration of the Halo. There are 64 setups numbered 0-63. All the Multisetups are user programmable except 63, the factory setup.

A Multisetup includes ALL the following parameters: • Preset/Volume/Pan/Arp assignments for each of the 16 MIDI channels. • Multisetup Name • ALL Controllers menu parameters • ALL Global Menu parameters, except… User Key Tuning Tables • ALL Arp Menu parameters, except… User Arp Patterns • ALL MIDI Menu parameters, except… MIDI Program Change->Preset Map

When a Multisetup is selected, it overwrites the current Preset/Vol/Pan/Arp selections on all MIDI channels. It also overwrites the Controllers, Global, Arp, and MIDI menu parameters (with the exceptions noted above).

If you make changes to any of these menus, Halo will retain the changes, even if power is turned off. They are of course, overwritten when you restore a Multisetup.

Restoring Halo contains 64 Multisetup locations. These are all User locations except Multisetups location 63, which is a factory deﬁned Multisetup. Multisetups can be restored using a MIDI Bank Select command. Select: cc00 = 80, cc32 = 00, (dec) then send a Program Change command corresponding to the Multisetup you wish to select.

Beats Halo contains a 16-track play-only sequencer that is optimized for live performance and groove creation. Halo contains dozens of special 16-part Beats Riffs created by some of the best producers in the business. Beats Riffs are normally used in conjunction with a “bts:” preset containing the appropriate percussion mapping, but any preset can be selected and used.

The Beats channel is selected from the Beats enable screen in the Arp/Beats menu.

Here’s how it works. Each of the 16 parts is assigned to a trigger key on the selected Trigger MIDI channel. Each part is brought in or out by pressing that key. Keys can also be Latched (press the key once to turn the part on, press it again to turn the part off). Other control keys allow you to Mute All Parts, Clear All Parts, and Start & Stop the beat. The 16 parts are arranged in the following manner:

For each Beats Riff, you have 2 Grooves, 4 Fills which correspond to the four parts of the Main and Alternate groove, and 4 Instrument parts. By adding and removing parts, you control the complexity of the groove. _ Beats (bts:) Riffs are Each part can also be scaled by Key Velocity, allowing you to fade parts in special 16-part riffs made and out (if velocity is routed to volume) as you play, or can be Transposed especially for use with Beats over a six octave range. mode.

48 ENSONIQ Arp/Beats Menu Beats Controllers

Beats Controllers Beats can be controlled using the front panel real-time controllers or external MIDI continuous controllers. Controllers are patched to Beats via the Preset PatchCords located in the Edit menu. The following Preset PatchCord destinations control Beats.

Beat Velocity Group 1-4 (BtsVelG1 -> BtsVelG4) Parts assigned to one of the four Beats groups can have their velocity scaled by the controller input. Since most “bts” presets have velocity controlling volume, this control can be used to mix the relative levels of the Groups. Beats velocity works as a percent addition. An input value of 0 (or no Cord) means change the velocity by 0%. A full scale modulation setting of 100% in the PatchCord adds 100% to the velocity value 100% + 100% = 200%. A PatchCord setting of -100% subtracts 100% from the velocity (making it 0). Beat velocity scalings are reset with a preset change.

Beat Xpose Group 1-4 (BtsXpsG1 -> BtsXpsG4) Parts assigned to one of the four Beats groups are transposed by the controller input. Transpose works by shifting the keyboard position and not by changing the tuning of individual notes. Therefore, on a Beats presets (bts), where different instruments are assigned to each key, Transpose has the effect of changing the instrument used by a particular part. This control ADDS to the Part Transpose set in the Beats Transpose screen (page 53). Beat transpose offsets are reset with a preset change.

Velocity can get complicated, but works according to this rule: WHICHEVER CONTROL WAS LAST CHANGED TAKES OVER

When interacting with the Group Velocity scale control, the Busy control ignores group velocity even when it is set to zero, enabling and disabling parts as necessary. If the Group Velocity is changed after the Busy control, it takes control, scaling parts as it deems necessary.

The Busy control does take the Part velocity into account when adding and subtracting parts. If a part has a velocity of 0%, it is removed from the list of parts that the Busy control adds or subtracts. Therefore, you can use the Part Velocity control to remove parts you don’t want to hear.

56 ENSONIQ Arp/Beats Menu Arpeggiators

Arpeggiators An arpeggiator moves a pattern of notes sequentially over a range of the keyboard. Halo has the unique ability to play a different arpeggiator on each MIDI channel! Arpeggiator settings can be defined as part of the preset (using the Arp parameters in the Preset Edit menu), or globally in the Arpeggiator menu. The preset and master arpeggiators have the same parameters which we define in this chapter. The Arp field in the main screen defines which arpeggiator settings will be used. “M” uses the master Arpeggiator settings and on/off status (as defined in the Arpeggiator menu). “P” uses the preset’s arpeggiator settings and on/ off status (as defined in the Edit menu). Choosing “On” uses the preset’s arpeggiator settings regardless of whether or not it is turned on in the Edit menu and Off turns off the arpeggiator regardless of the settings and status specified in either menu.

_ SAVE your Arp setups and name them using the “Save Arp Settings in the Setup To” function located in the Preset are Used Multi menu. See“Saving Multisetups” on page 42. C01 V127 P00 A:P USER 0473 arp: Sine Drum

All arpeggiators share Halo’s master clock and its current setting. The master clock can be Halo’s internal clock or an external MIDI clock (page 82). Although the arpeggiators use the master clock setting, the tempo divisor can be unique for each arpeggiator setup. Arpeggiator modes include up, up/down, forward assign, backward assign, forward/backward assign and random as well as play Patterns. Patterns are pre-recorded sequences of notes and rests. All key-on notes play the pattern. For example, if you play a chord, all the notes in the chord play the pattern in harmony. Halo contains 200 factory patterns and 100 user deﬁnable patterns.

Halo Operation Manual 57 Arp/Beats Menu Master Arpeggiator Parameters

Arp Controllers The Arpeggiators can be controlled using the front panel real-time controllers or external MIDI continuous controllers. Controllers are patched to Arps via the Preset PatchCords located in the Preset Edit menu. See “Preset Patchcords” on page 165. The following Preset PatchCord destinations control the Arpeggiators.

Arpeggiator Resolution (ArpRes) This control changes the Arpeggiator Note Value, which deﬁnes the length of the notes when playing arpeggiated chords. It adds to the note value set in the Arpeggiator Note Value screen. See “Note Value” on page 60.

Arpeggiator Extension (ArpExt) This control changes the Arpeggiator Extension Count. It adds to the extension count programmed in the Arpeggiator Note Value screen. See “Extension Count” on page 62.

Arpeggiator Velocity (ArpVel) This control changes the Arpeggiator Velocity Value. It scales the velocity value set in the Arpeggiator Note Value screen. See “Velocity” on page 61.

Arpeggiator Gate (ArpGate) This control changes the Arpeggiator Gate Time. It adds to the gate time set in the Arpeggiator Gate Time screen. See “Gate Time” on page 61.

Arpeggiator Interval (ArpIntvl) This control modulates the Arpeggiator Extension Interval. It adds to the extension programmed in the Arpeggiator Extension Interval screen. See “Extension Interval” on page 62.

Master The Master Arpeggiator is defined in the Arp menu.

Velocity The Velocity parameter determines the velocity at which each note arpeg- giates. Velocity can be deﬁned by the velocity value speciﬁed (from 1 through 127), or by the actual velocity of the played note (played). Bear in mind that velocity values do not have an effect on the sound unless the preset is programmed to respond to velocity.  Controller Knob O is programmed to control Arp Velocity. MASTER ARPEGGIATOR Velocity played

Gate Time The Gate Time parameter works together with the Note Value parameter. Just as Note Value deﬁnes the length of a note, the Gate Time sets the percentage of the Note Value time played. This can have a dramatic effect on the sound depending on how the envelope generators are programmed.  Controller Knob P is programmed to control Arp Gate Time. MASTER ARPEGGIATOR Gate 100%

Extension Count The Extension Count parameter speciﬁes how many times the Extension Interval is carried out. With an Extension Count of 0, the arpeggio plays only the notes pressed. With an Extension Count of 1, the arpeggio plays the notes pressed, then plays the same notes (in the same order), transposed by the Extension Interval amount. The cycle is then repeated.

MASTER ARPEGGIATOR Extension Count 4

For example, with the Extension Interval set to 12 (an octave) and an Extension Count of 2, and with the Arpeggiator Mode set to Fwd Assign, if you played E2, then C2, then G2, the arpeggiated sequence would consist of: E2, C2, G2, then E3, C3, G3, and then E4, C4, G4. The Extension Count values range from 0 through 15. Refer to the following illustration.

Extension Interval The Extension Interval speciﬁes the additional intervals played when you press a key. For example, suppose you played C2 with an Interval of 7 (a Major 5th), Up mode, and an Extension Count of 2. The arpeggio alternates between C2 and G2.

The Extension Interval values range from 1 through 16.

Pre-Delay The Pre-Delay value determines how long the arpeggiator is delayed before becoming active after the ﬁrst “note-on.” During the pre-delay period, notes are played normally (as if the arpeggiator was off). After the pre-delay period has elapsed, the arpeggiator kicks in. Once you release all the keys on the controller, the pre-delay starts over with the next note-on. In combination with the Duration parameter, Pre-Delay lets you create many more variations in the arpeggio patterns. Please refer to the diagram on page 65. You can play the preset normally as long as you don’t hold the notes longer than the Pre-Delay. If you do, the arpeggiator starts in. When used in conjunction with multiple arpeggiators, Pre-Delay allows you to offset the time between the different patterns.

MASTER ARPEGGIATOR Pre-Delay off

Halo Operation Manual 63 Arp/Beats Menu Master Arpeggiator Parameters

Duration This parameter defines how long the arpeggiator plays before stopping. The Duration is specified in note values. Therefore if an arpeggio were running at a 16th Note Value and the Duration were set to a whole note, the arpeggiator would play 16 steps before stopping. After the duration has elapsed, the arpeggiator remains inactive until the key is released. If Duration is set to Off, the arpeggio repeats as long as the notes are held (Infinite Duration).

MASTER ARPEGGIATOR Duration 1 / 1d

Duration can be used to modify the patterns and increase the possible pattern combinations and variations. Because this parameter limits the length of arpeggiator play time, it can change the arpeggio pattern when the Duration is less than the length of the arpeggio. You can set the arpeggio to repeat continuously using the Recycle function described below.

Post-Delay This parameter is only relevant when both the “Duration” and “Recycle” parameters are not in the “Off” state. The Post-Delay value determines how long the arpeggiator is delayed after the Duration period. Please refer to the diagram on page 65. During the post-delay period, notes are played normally (as if the arpeggiator was off). After the post-delay period has elapsed, the arpeggiator either jumps to the beginning of the Pre-Delay period or to the beginning of the Duration period depending on the Recycle setting.

If the arpeggiator is playing an extension when the Duration expires, the notes in the extension will continue to sound during the Post-Delay (and Pre-Delay if on). On the next pass through the Duration period, the extension continues where it left off.

Post-Delay increases the number of possible variations in the beat and allows the recycle loop to be set to an exact measure of time.

Recycle Recycle enables the pattern or arpeggio to repeat. This parameter works together with the Duration and Pre/Post Delay parameters to allow the loop to be set to an exact measure of time. The “on/No-PreDelay” option bypasses the predelay period. With Recycle turned Off, the pattern or arpeggio stops at the end of the Post-Delay period.

When you edit a pattern, you are writing directly into memory—no Save command is required (however, you must exit the Arp module). This is different from the Edit menu where you must Save a preset before it will be overwritten. If you want to modify an existing pattern and keep the original, you must ﬁrst COPY the pattern you want to edit to another location using the function in the Save/Copy menu (See page 191).

Key Offset This parameter defines not the actual note of the arpeggiator playback, but instead specifies the amount of offset, in semitones, from the original note played. You can set a Key Offset from -48 to +48 for each step. For example, if you play a “C” on the keyboard with the Key Offset amount for the first step set to “+1,” the first step in the pattern will be “C#.”

Rest Instead of playing a note, you can deﬁne the step as a Rest. The Duration parameter speciﬁes the length of the rest. Rests can be tied together to form longer rests.

Skip This command simply removes the step from the pattern. The Skip feature makes it easy to remove an unwanted step without rearranging the entire pattern. You’ll be happy to know that the velocity, duration and repeat parameters are remembered if you decide to put the step back later.

End This command signals the end of the pattern. Any steps programmed after the step containing the End command are ignored.

Real-time Controller Use these three pages to assign sixteen real-time control sources. Each MIDI Assignment Controller is assigned a letter (A - P). The front panel Controller Knobs and sixteen MIDI controller numbers share the ﬁrst 12, A-L controller routings. These screens let you select which MIDI real-time controllers numbers will be received (from 1 to 31 and from 64 to 95) and which controller numbers will be transmitted over MIDI if the front panel controls are turned. The PatchCord routing and amount in the Preset Edit menu determine what effect the controller has on each preset. Real-time controllers are shown in the PatchCord menu as MIDI A through MIDI P. The Real-time Controller assignment also speciﬁes which controller numbers are transmitted when the “Knobs Output MIDI” is enabled (see “Knobs Output MIDI” on page 94).

3. Move the cursor to the lower line of the display and rotate the Data Entry Control to select the control to be calibrated. The choices are: • Mod Wheel • Pitch Wheel • Foot Pedal • Aftertouch

4. Press Enter to select a control, then follow the instructions given in the display. You will be asked to mover the control through its entire range (minimum through maximum), then press Enter. 5. In the case of the Pitch Wheel, you ﬁrst move the wheel through its min-max range and leave the wheel resting in its center position. Then press Enter.

Tempo Controller This function allows a MIDI controller to change the Base Tempo of the Master Clock. The Master Clock is used by the arpeggiators, clock divisor PatchCords, tempo-based envelopes and synced LFOs. (See “Clock Modulation” on page 106.) You can assign any controller number from 0- 31, mono key pressure, or the Pitch Wheel to change the Global Tempo.

A different controller can be used to change the tempo up or down. The Pitch Wheel can be assigned to both the up and down parameters to vary the tempo up and down from a single controller. If any other controller is assigned to both the up and down parameters, Halo redeﬁnes the center of the controller’s range as zero (so it acts like a pitch wheel).

MIDI Controller values are added to the Base Tempo with a range of ±64. When the controller is set to “off” the tempo returns to its original setting. Controllers are only recognized on the selected MIDI channel, unless Halo is in Omni mode, in which case all channels are accepted. This control has no effect when using an external clock.

Halo Operation Manual 81 Controllers Menu Base Tempo

Base Tempo Halo contains an internal Master Clock which runs the arpeggiators, synchronizes the LFOs when in tempo-based mode, controls the times of tempo-based envelopes, and can be used as a modulation source in the PatchCords section.

You’ll notice that there are two tempo values shown in the display. • Base Tempo - This is the base tempo setting before being modified by the Tempo Controller (if engaged). See “Tempo Controller” on page 81.  The Arp/Beats LED • (Current Tempo) - This is the actual tempo! The current tempo is flashes in time with the Base equal to the base tempo modulated by the MIDI controller specified in Tempo. the Tempo Controller screen.

Master Transpose/ The Transpose parameter transposes the key of all presets, in semitone Tune intervals. The transpose range is ± 24 semitones. Master Tune adjusts the ﬁne tuning of all presets so that you can tune Halo to other instruments. The master tuning range is ± 1 semitone in 1/64th semitone increments (1.56 cents). A master tune setting of “+00” indicates that Halo is perfectly tuned to concert pitch (A=440 Hz).

MASTER TRANSPOSE TUNE +00 semitones +00

Master Bend Range The Master Bend Range parameter sets the range of the pitch wheel. This affects only presets that have their individual Pitch Bend range (deﬁned in the Preset Edit menu) set to Master. See page 160. The maximum pitch bend range is ±12 semitones or one octave in each direction.

Mix Output The Mix Output parameter allows you to override the routing assignments made in each preset and instead assign the outputs according to MIDI channel. For each of the 16 MIDI channels, you can select Send 1-4, or Preset. When Preset is selected, the output assignment deﬁned in the Preset Edit menu is used.

MIX OUTPUT channel 16: Send 1->main

Indicates that the dry signal is routed to the Main output jacks.

The Output Routing ﬁeld (pointed to by the arrow) reﬂects the true routing of Send 2 or Send 3 to either: 1) the effects processor input or… 2) the rear panel submix jacks.

Since the Sub 1 output is NOT being used, the signal is routed through the effects processors, then on to the main outputs. If a plug were inserted into one of the Sub 1 jacks the destination ﬁeld would read “Sub1” for Send 2 and the dry signal would be routed directly to the Sub 1 outputs on the back panel.

MIX OUTPUT channel 15: use preset

 Send Routings The Sends function as effect processor inputs (effect sends). Send 2 is also Send 1 - Main Outputs used to route sounds to the Sub 1 outputs on the back panel. When a plug Send 2 - Subout 1 or Main Outs is inserted into the associated Submix jack on the back panel, the Dry Send 3 - Main Outs portion of the Send is disconnected from the effects processor and the Send 4 - Main Outputs signal is routed directly to the output jack. The Arrow points to the actual output routing. If you don’t want the wet portion of the signal in the main mix, turn down the Send Level. The entire Send is disconnected from the Effects Processors even if only one plug is inserted into the Submix jack. The four Effect Sends allow you to get the most out of the two effect processors. For example, with Effect B set to an echo algorithm, you could route one MIDI channel to Send 3 and set the effect amount to 80%. Another MIDI channel could be routed to Send 4 with an effect amount of only 5%. This is almost like having two different effects! The Mix Output function is also useful when sequencing since it lets you route speciﬁc MIDI channels to speciﬁc Sub outputs (on the back panel) where there they can be processed with EQ or other outboard effects.

Halo Operation Manual 87 Global Menu Master Effects

Master Effects The digital effect processors can be programmed as part of the preset (using the Preset Edit menu) so that effects will change along with the preset. However, there are only two effect processors, and so you cannot have a different effect on each preset when in Multi mode. The Master Effects settings assign the effect processors “globally” for all presets to provide a way to use the effects in Multi mode. Detailed information is presented in the Effects chapter (see Effects on page 173).

Effects Mode The FX Mode page enables or bypasses the effects. When the FX Mode is set to “bypass,” the effects are turned off on a global scale. This includes Effects programmed in the preset.

98 ENSONIQ Programming Basics

This chapter explains how Halo sounds are constructed and contains important background information on how to create your own custom presets. Your initial involvement with Halo will most likely be using the existing presets and selecting MIDI channels. While the factory presets are very good, there are some things you will probably want to change eventually, perhaps the LFO speed, the ﬁlter frequency or the attack time. You may also want to make your own custom presets using complex modulation routings. This module will do far more than you ever imagined and there are whole new classes of sound just waiting to be discovered. Each preset can consist of up to four instrument layers. Each of the four layers can be placed anywhere on the keyboard and can be crossfaded or switched according to key position, velocity, or by using a real-time control such as a wheel, slider, pedal, LFO or envelope generator. A preset can also be “linked” with up to 2 more presets creating additional layering or splits. Halo has an extensive modulation implementation using two multi-wave LFO’s (Low Frequency Oscillators), three multi-stage envelope generators and the ability to respond to multiple MIDI controllers. You can simultaneously route any combination of these control sources to multiple destinations. There are 512 user locations (USER Banks 0-3) available to store your own creations or edited factory presets. It’s easy and fun to edit or create your own unique presets.

Halo Operation Manual 99 Programming Basics Modulation

Modulation To modulate means to dynamically change a parameter, whether it be the volume (amplitude modulation), the pitch (frequency modulation), and so on. Turning the volume control on your home stereo rapidly back and forth is an example of amplitude modulation. To modulate something we need a modulation source and a modulation destination. In this case, the source is your hand turning the knob, and the destination is the volume control. If we had a device that could turn the volume control automatically, we would call that device a modulation source.

Turning the volume control back and forth on your home stereo is an example of Amplitude Modulation.

Halo is designed so that each of the variable parameters, such as the volume, has an initial setting which is changed by a modulation source. Therefore in the case of volume, we have an initial volume that we can change or modulate with a modulation source. Two main kinds of modulation sources on Halo are Envelope Generators and Low Frequency Oscillators. In the example above, an envelope generator could be routed to automatically turn the volume control as programmed by the envelope. Or, a low frequency oscillator could be routed to turn the volume up and down in a repeating fashion. Positive modulation adds to the initial amount. Negative modulation subtracts from the initial amount.

Summing Nodes All the modulation inputs on Halo are summing nodes. This means that you can connect as many modulation sources as you want to an input (such as Pitch or AmpVol). Modulation sources are simply added algebraically— connecting two knobs one set to -100 and the other set to +100 yields a net value of zero.

100 ENSONIQ Programming Basics Modulation Sources

Modulation Modulation sources include Envelope Generators, Performance Controllers and Low Frequency Oscillators. In the previous example, an envelope generator Sources was routed to automatically turn the volume control as programmed by the envelope, or, a low frequency oscillator could be routed to turn the volume control up and down in a repeating fashion. The following is a list of the modulation sources used in Halo.

Halo Operation Manual 101 Programming Basics Modulation PatchCords

Random Sources Random modulation sources can be used when you want the timbre of the sound to be “animated” in a random or non-consistent manner. • Key Random 1 & 2 generate different random values for each layer which do not change during the note. • The White & Pink Noise Generators produce varying random values. Both white and pink noise sources are low frequency noise designed for control purposes. Either noise source can be ﬁltered even more by passing it through a lag processor. • The Crossfade Random function generates the same random value for all layers in a preset. This source is designed to be used for crossfading and cross-switching layers, although you may ﬁnd other uses.

Modulation When setting up modulation with the Halo, you deﬁne a modulation source and a modulation destination. Then, you connect the source to the PatchCords destination using “PatchCords.” Halo’s PatchCords are connected in the software. Halo has 24 general purpose PatchCords for each layer.  The controller Knobs You can connect the modulation sources in almost any possible way to the assignments printed on the front modulation destinations. You can even modulate other modulators. Each panel are the system defaults.

102 ENSONIQ Programming Basics Envelope Generators

Envelope An envelope can be described as a “contour” which is used to shape the sound over time in a pre-programmed manner. There are three envelope Generators generators per layer and all of them are the rate/level type. This is how the rate/level (time based) envelopes work: When a key is pressed, envelope starts from zero and moves toward the Attack 1 Level at the Attack 1 Rate. As soon as it reaches this ﬁrst level, it immediately begins the next phase and moves toward the Attack 2 level at the Attack 2 rate. As long as the key is held down, the envelope continues on through the Decay 1 and Decay 2 stages. If the key is still held when the envelope reaches the end of Decay 2, it simply waits there for you to release the key. When you release the key, the envelope continues into the Release 1 and Release 2 stages, stopping at the end of the Release 2 stage. Halo’s envelope generators provide great ﬂexibility for programming both complex and simple envelopes. _ If two adjacent segments have the same level in a “time- Dcy1 based” envelope, the segment Atk2 will be skipped. Adjacent Dcy2 segments must have different levels for the rate control to work. Rls1

You can adjust the time of each stage to create myriad envelope shapes, which in turn shape the sound over time.

Using Halo’s Volume Envelope, you can simulate the different types of natural instrument volume envelopes by programming them appropriately.

Halo Operation Manual 103 Programming Basics Envelope Generators

Tempo-based Envelopes Tempo-based envelopes are based on Time which is controlled by the Master Tempo (located in the Global menu). The Master Tempo rate scales the time of the Tempo-based envelope segments. The Master Tempo can be set to use an external MIDI clock so that the envelope times can be synchronized to external sequencer or arpeggiator tempo changes. See page 82.

Tempo-Based Envelopes

Envelope Repeat The Envelope Generators can also be made to repeat. When the envelope repeat function is On, the Attack (1&2) and Decay (1&2) stages will continue to repeat as long as the key is held. As soon as the key is released, the envelope continues through its normal Release stages (1 & 2).  Only the Filter and Auxiliary Envelopes have the repeating feature. Atk2 Rls1

The diagram above show how the looping envelopes work. When the key is pressed the envelope goes through its regular Attack 1, Attack 2, Decay 1 and Decay 2 stages. In non-looping mode, the envelope would hold at the end of the Decay 2 stage until the key was released. In looping mode however, it jumps back to the Attack 1 stage and repeats the ﬁrst four stages. It continues to loop through these four stages until the key is released where it immediately jumps to the Release 1 stage.

104 ENSONIQ Programming Basics Low Frequency Oscillators (LFOs)

Low A Low Frequency Oscillator or LFO is simply a wave which repeats at a slow rate. The Halo has two multi-wave LFOs for each channel. The LFO Frequency waveforms are shown in the following illustration. Oscillators Random Triangle Sawtooth (LFOs)

The sine wave looks smooth, and changes the pitch smoothly. The square wave changes abruptly and abruptly changes from one pitch to another. The sawtooth wave increases smoothly, then changes back abruptly. The sound’s pitch follows the same course. Controlling the pitch of an instrument is an easy way to hear the effects of the LFO waves.  Try combining the Like the Auxiliary Envelope, LFOs can be routed to control any real-time Pattern LFOs, or controlling the function such as Pitch, Filter, Panning, or Volume. A common use for the amount of one with another, or LFO is to control the pitch of the sound (LFO -> Pitch). This effect is called combining them with the clock vibrato and is an important performance effect. Many presets use this divisors. routing with the modulation wheel controlling “how much” LFO modulation is applied. Another common effect, Tremolo, is created by controlling the volume of a sound with the LFO (LFO -> Volume).

Halo Operation Manual 105 Programming Basics Clock Modulation

You might use the LFOs to add a slight bit of animation to the sound by routing the LFO to control the ﬁlter. For this effect, set the LFO “amount” low for a subtle effect. When a PatchCord amount is a negative value, the LFO shape is inverted. For example, inverting the sawtooth wave produces a wave that increases abruptly, then smoothly glides down.

Negative Amount - +

Clock You can use the Master Clock as a modulation source, to trigger the Filter or Auxiliary Envelope generators, trigger Sample Start, synchronize the LFOs, Modulation or directly as a square wave modulation source. The Clock source is available in eight divisions (octal whole note, quad whole note, double whole note, whole note, half note, quarter note, eighth note, sixteenth note). You can use the different rates separately or in conjunction to create complex “synchro-sonic” rhythm patterns. You can also use a MIDI Clock as the Master Clock to synchronize to an external MIDI device such as a drum machine or sequencer. (See Master Tempo in the Global menu.)  Envelopes are triggered Clocks are routed exactly like the other modulations sources using the on the positive going edge of the PatchCords. The PatchCord Amount MUST be positive (+) for the clock to clock. LFOs are triggered on the pass. By modulating the PatchCord Amount, you can route the divided negative going edge of the clock. clocks using real-time controllers or other modulation sources. When an LFO is triggered by a clock, the LFO wave resets to zero every time the clock wave goes low. If the LFO rate is close to the clock rate, the LFO virtually synchronizes with the clock. If the two rates are far apart, the waveform of the LFO will be mildly or radically altered.  The tempo of the master clock is set in the Global menu. Triggered LFO

LFOs can also be perfectly synchronized with the clock at any of 25 note divisions. This allows you to create very cool “synchro-sonic” effects that work perfectly at any tempo. Choosing one of the note divisors in the LFO rate screen selects the synced LFO function. There are many possibilities for clock modulation and retrigger. For example, you can create a repeating six segment curve of any shape by triggering the Filter or Auxiliary Envelope generators with the clock. A few other possibilities are listed below. LFO Synced to 1/4 Note Clock • Turn different voice layers on and off using different clock divisors. • Switch between Auxiliary and Filter Envelope retriggering using a slider or footswitch. • Retrigger LFOs or Envelopes using noise or other LFOs to create random or semi random effects. • Alter the LFO waveform by modulating the rate of a triggered LFO. • Route multiple clocks with different divisors to the same destination (such as pitch) to create complex patterns.

A MIDI footswitch could be used as the input to the lag which acts to slow down the instantaneous change of the switch. The slowly changing output value is then routed using a layer patchcord to crossfade between layers or change the speed of an LFO.

The preset ramp instantly resets when all notes have been released and the next ﬁrst key on the MIDI channel is pressed.

Large values produce fast ramps and small values produce slow ramps. Multiple inputs can be connected to the ramp rate (just like all the other destinations in Halo). The patch below shows an application for the Preset Ramp which generates an adjustable decay envelope ONLY on the ﬁrst note played to bring in the sound from another layer. Instead of routing the output to the Amp Volume you could just as easily route it to control Pitch, LFO Speed or any other destination you can think of.

112 ENSONIQ Programming Basics Preset Modulation Processors

Using the Modulation processors are inserted into a modulation routing as shown in Modulation the following diagram. Processors The modular analog synthesizers of yesteryear were incredibly ﬂexible, partly because processing devices could be connected in any order. Modulation processors are designed according to this modular concept. They can be linked and used in a wide variety of ways limited only by your imagination. Consider the following example:

Velocity ~ Switch Pitch

Cord Cord Switch On when Switch value Velocity > 0 is Scaled by Cord Amount

The patch illustrated above is programmed by setting the PatchCord screens as shown below.

L1 PATCHCORD #01 Vel+- -> Switch +100

L1 PATCHCORD #02 Switch -> Pitch +022

This particular modulation shifts the overall pitch up a fifth when the key velocity exceeds 64. Velocities below 64 play at normal pitch. Notes with velocities of 64 and above are raised a perfect fifth. The Velocity “~” source scales the played velocity around zero. In other words, low velocities (below 64) will have negative values and high velocities (64 and above) will be positive. A velocity of 64 would be zero. The Switch module only outputs a “1” if the input value is greater than zero. This digital “1” value can be scaled through the attenuator on the PatchCord to raise or lower the pitch by any amount. In this case, a scaling value of +22 raises the pitch by a perfect fifth. The amount of the PatchCord on the input to the switch is unimportant because ANY velocity value equal or greater than 64 will flip the switch. If the input PatchCord amount were a negative value however, the action of the velocity would be reversed and velocities less than 64 would raise the pitch and velocities equal or greater than 64 would play the original pitch.

Halo Operation Manual 113 Programming Basics Preset Modulation Processors

But what if you want the velocity switch point to be something other than 64? Thanks to modulation processors, it can be done. Here's how.

Velocity ~

Cord Switch Pitch 21 Cord DC Switch On when Switch value Velocity > 0 is Scaled by Cord Amount Cord

Connect the DC level to the input of the switch along with the velocity value. Note that more than one modulation source can be applied to the input of a processor. DC offset adds a ﬁxed value based on the PatchCord Amount setting. If applied to the switch along with the velocity, it changes the velocity value required to trip the switch. By setting the DC amount to a negative amount, higher velocity values are required to trip the switch. Setting the DC value to a positive value would bring the velocity switch point down. The PatchCord screens for this patch are shown below.

L1 PATCHCORD #01 Vel+- -> Switch +100

L1 PATCHCORD #02 DC -> Switch -021

More Examples To derive a smooth random function you could route the Pink Noise generator through one of the Lag Processors. A smooth random wave is useful in small amounts to add a degree of natural variation to timbre when routed to filter cutoff. Normal pink noise is low pass filtered audio frequency noise with a 3 dB/octave slope to give equal energy per octave. Halo pink noise is actually more like very low frequency filtered noise, but it is perfect for use as a random control source.

The Quantizer can generate interesting whole-tone scales when envelope generators or LFOs are routed to the input. The quantizer turns a smoothly changing input signal into a series of steps. By routing the output of the quantizer to Pitch and adjusting the PatchCord amounts, you can control both the number of steps and the pitch interval of each step.

The input PatchCord amount controls how many steps will be generated. With a sawtooth wave (LFO+) feeding the input and the PatchCord amount set to 100%, sixteen steps are generated.

To understand how a ﬁlter works, we need to understand what makes up a sound wave. A sine wave is the simplest form of sound wave. Any waveform, except a sine wave, can be analyzed as a mix of sine waves at speciﬁc frequencies and amplitudes.

Any waveform can be analyzed as a mixture of sine waves.

One way to represent complex waveforms is to use a chart with frequency on one axis and amplitude on the other. Each vertical line of the chart represents one sine wave at a speciﬁc amplitude and frequency.

Halo Operation Manual 117 Programming Basics Dynamic Filters

What is a Filter? Most sounds are complex waves containing many sine waves of various amplitudes and frequencies. A ﬁlter is a device which allows us to remove certain components of a sound depending on its frequency. For example, a low-pass ﬁlter lets the low frequencies pass and removes only the high frequencies as illustrated in the following diagram.

100 Cutoff Frequency

40 80 160 360 720 1440 2880 ... Frequency

A ﬁlter that lets only the high frequencies pass is called a high-pass ﬁlter as illustrated in the following diagram.

A notch filter is just the opposite of a band-pass filter and is used to eliminate a narrow band of frequencies. Another control found on traditional filters is called Q or resonance. A lowpass filter with a high Q emphasizes the frequencies around the cutoff frequency. The following chart shows how different amounts of Q affect the low-pass filter response. In terms of sound, frequencies around the cutoff tend to “ring” with high Q settings. If a filter with high Q is slowly swept back and forth, various overtones are “picked out” of the sound and amplified as the resonant peak sweeps over them. Bells and gongs are real world examples of sounds which have a high Q.

Halo Operation Manual 119 Programming Basics Dynamic Filters

Another characteristic of a filter is the number of poles it contains. Tradi- tional synthesizer filters were usually either 2-pole or 4-pole filters. The Halo has selectable 2, 4, and 6-pole low-pass filters. The number of poles in a filter describes the steepness of its slope. The more poles, the steeper the filter's slope and the stronger the filtering action. The tone controls on your home stereo are probably one-pole or two-pole filters. Parametric equalizers are usually either two-pole or three-pole filters. In terms of vintage synthesizers, Moog and ARP synthesizers used 4-pole filters, Oberheim and Eµ synthesizers were famous for their 2-pole filter sound.

6-pole 4-pole 2-pole Amplitude Lowpass Lowpass Lowpass

Frequency

Using a filter, we have a way to control the harmonic content of a sound. As it turns out, even a simple low-pass filter can simulate the response of many natural sounds. For example, when a piano string is struck by its hammer, there are initially a lot of high frequencies present. If the same note is played softer, there are fewer high frequencies generated by the string. We can simulate this effect by routing keyboard velocity to control the low-pass filter. The result is expressive, natural control over the sound. If you use an envelope generator to control the cutoff frequency of a filter, the frequency content can be varied dynamically over the course of the note. This adds animation to the sound as well as simulates the response of many natural instruments.

120 ENSONIQ Programming Basics Dynamic Filters

Parametric Filters A more complex type of filter is called a parametric filter or Swept EQ. A parametric filter allows control over three basic parameters of the filter. The three parameters are: Bandwidth, Frequency and Gain. The Bandwidth allows you to select the width of the range of frequencies to be boosted or cut, the Frequency defines the center frequency of the bandwidth, and the Gain parameter either boosts or cuts the frequencies within the selected band by a specified amount. Frequencies not included in the selected band are left unaltered. This is different from a band-pass filter which attenuates (reduces) frequencies outside the selected band.

+18 dB Freq. Boost Parametric Filter 0 dB

Amplitude Bandwidth Cut -18 dB Frequency

The parametric filter is quite flexible. Any range of frequencies can be either amplified or attenuated. Several parametric sections are often cascaded in order to create complex filter response curves. If four parametric filter sections were cascaded, it would be possible to create the following complex filter response.

Filters A and B represent two different complex filters or “frames.” Changing a single parameter, the Morph, changes many complex filter parameters simultaneously. Following along the Morph axis you can see that the filter response smoothly interpolates between the two filters. This is the essence of the Z-plane filter. Through the use of interpolation, many complex parameters are condensed into one manageable entity. Consider, as an example, the human vocal tract, which is a type of complex filter or resonator. There are dozens of different muscles controlling the shape of the vocal tract. When speaking, however, we don't think of the muscles, we just remember how it feels to form the vowels. A vowel is really a configuration of many muscles, but we consider it a single object. In changing from one vowel to another, we don't need to consider the frequencies of the resonant peaks. You remember the shape of your mouth for each sound and interpolate between them. This Z-plane filter sweep can be controlled by an envelope generator, an LFO, modulation wheels or pedals, keyboard velocity, key pressure, and so on. In fact, any of the modulation sources can control the Z-plane filter. Because creating the complex filtering is difficult and very time consuming, we have created 50 different filters and installed them permanently in ROM for your use. You simply select and use the filters in a manner similar to choosing an instrument. Because there are so many types of instruments and filters to choose from, the number of possible permutations is staggering.

Instrument This is the sampled sound wave. The pitch of the instrument can be modulated by any modulation source. The sample start point can be changed only at the time the note is played.

Z-Plane Filter The Z-Plane Filter is used to shape the harmonic content of an instrument. The filter envelope is commonly used to shape the harmonic content dynamically over time but the filter frequency can be modulated by any source. The Q parameter can be modulated only at note-on time. There are 50 types of filters available. See “Halo Filter Types” on page 148 for a complete list of the filters.

Digitally Controlled Ampliﬁer (DCA) Together with the Volume Envelope, the DCA is used to shape the volume contour of a sound. The DCA can be controlled by any modulation source. Velocity is often used as a modulation source for the DCA so that the harder you play, the louder the sound becomes.

Pan Adjusts the balance of sound to the left and right channels. Pan can be modulated by any modulation source.

Halo Operation Manual 123 Programming Basics MIDI Channels & Real-time Controls

MIDI Channels The MIDI real-time controllers may seem confusing at ﬁrst, but they are really very simple once you understand them. You already know that there & are 16 MIDI channels per MIDI cable. Each MIDI channel uses three basic Real-time types of messages; note on/off, preset changes, and continuous controller messages. Halo can also send real-time control information, which simply Controls means control occurring in real-time or “live.” Real-time control sources include such things as controller knobs, pitch wheels, modulation wheels, control pedals and aftertouch. These are used to add more expression or control. The front panel control knobs send out real-time controller information on separate continuous controller numbers. There is a set of 32 continuous controller numbers for each MIDI channel. Some continuous controllers, such as modulation wheel, volume, and pan have standardized numbers. For example, volume is usually sent on continuous controller #7. The front panel controller knobs on are pre-programmed to control the Halo.  The following MIDI controls are automatically routed in Halo: MIDI MIDI MIDI MIDI Channel 1 Channel 2 Channel 3 Channel 16

Pitch Wheel pwh Note Note Note Note Modulation Wheel 01 On/Off On/Off On/Off On/Off Pedal 04 Program Program Program Program Volume 07 Change Change Change Change Pan 10 Expression 11 Continuous Continuous Continuous Continuous Controllers Controllers Controllers Controllers

Any MIDI controller can be routed to any modulation destination. First, you have to know which controller numbers your keyboard transmits. Most modern MIDI keyboards let you select a controller number for each control on the keyboard. For example, it may let you select a number from 0-31 for the data slider. The realtime controller numbers that the keyboard transmits must match the numbers Halo is receiving, otherwise nothing will happen when you move the controls. Suppose you wanted to send the four data knobs on another keyboard via MIDI to Halo. Halo can handle up to 16 MIDI controllers (A-P) of your choosing. “MIDI A-P” are simply names for the internal connections that link external MIDI continuous controllers to the PatchCord section of Halo. There are two parts to the connection. First, MIDI controller numbers are assigned to the letters A-P in the Controllers menu. Next, the letters A-P are connected to synthesizer control parameters in the PatchCord section of the Preset Edit menu. The PatchCord Amount scales the amount of each controller by a positive or negative value.

The factory presets have the MIDI A-P controls connected to standard synthesizer functions (marked on the front panel). By choosing any four of the 16 standard functions, the four sliders on your keyboard will work the

MIDI A-P are internal connections which simultaneously carry front panel controller knob data and MIDI continuous controller data.

The front panel controller knobs work just like MIDI real-time controllers. The four controller knobs can be assigned to the ﬁrst 12 letters A-L. The front panel knob and incoming MIDI controller messages assigned to that letter, both control the same parameter that you select in the PatchCord screen. Letters M-P can be used to route 4 more external MIDI controllers.

Halo Operation Manual 125 Programming Basics MIDI Channels & Real-time Controls

Bank Select When the original MIDI specification was developed, no synthesizer had Commands more than 40 preset locations. At that time being able to select up to 128 presets didn’t seem like much of a limitation. So it was that the original MIDI specification provided for the selection of up to 128 presets. Musicians wanted MORE presets and so the MIDI specification was later amended to include Bank Select Commands. It was decided that Bank Select Commands would use Continuous Controllers 0 and 32 to allow the selection of up to 16,384 banks of 128 presets (over two million presets). Because Bank Selects are implemented using Continuous Controllers, the Bank Selections can be made per channel. (This is getting better and better.) For each MIDI channel, you can select any of 16,384 banks and then one of the 128 presets in the bank. Of course no synthesizer has 16,384 banks (yet), but hey, it’s nice to know it’s possible (for that really BIG project). Continuous Controller (CC) 0 is the MSB (most significant byte) and CC 32 is the LSB (least significant byte). Normally you send both the MSB and LSB controllers to implement a bank change.  When you press the Halo remembers the MSB and the LSB that were last sent (or last changed Audition button, the Bank Select from the front panel). For example, if you have already set the Bank MSB to MSB and LSB are displayed on 04, you need only send the LSB to change banks within the Halo sound set. the top line of the display. See the MIDI Bank Select chart below. The selected bank remains selected until you change it (either via MIDI or by changing the bank from the front panel).

Transposing the The Transpose parameter lets you transpose the key of the current layer’s Instrument Instrument. Transpose works by shifting the keyboard position in semitone intervals relative to middle C. Use this parameter to transpose different layers apart by semitone intervals. For example, by transposing one layer by +7 semitones, it will track other layers at a perfect ﬁfth interval.

C-2 C-1 C0 C1 C2 C3 C4 C5 C6 C7 C8 G8

The range of transposition is -36 to +36 semitones.

140 ENSONIQ Preset Edit Menu Tuning

Tuning The Tuning parameter changes the pitch of the key in semitone and 1/64 semitone intervals.

L1 TUNING Coarse: +36 Fine: +63

Use the Coarse ﬁeld to shift the tuning by semitone intervals. Use the Fine ﬁeld to shift tuning by 1/64 semitones (or 1.56 cents) intervals.

Background: Transpose vs. Coarse Tuning Transpose works by shifting the keyboard assignment of the Instrument (as if you were sliding the keyboard up and down with the Instrument remaining in the same position). Coarse Tuning keeps the instrument placement on the keyboard and actually tunes the samples up using a digital process called interpolation. Use Course Tuning on drum instruments to change the pitch while keeping sample placement constant. Coarse Tuning can also be useful to slightly change the timbre of the instrument.

Ampliﬁer This parameter sets the initial volume and pan position of the current layer. These values can be changed using any Real-time Controller set up in the PatchCords. The value range for the volume is from -96 dB to +10 dB. 0 dB is the default setting. Routinely turning the volume up to +10 dB is not recommended because it doesn’t allow other modulation sources to increase the volume further.

L1 AMPLIFIER

Volume: +10dB Pan: 48L

This ﬁeld determines the initial Pan value for the current layer. The value range for Pan is from 64L to 0 (left) and 0 to 63R (right). Pan adjusts the volume into the left and right output channels relative to the Pan setting in the main Preset Select screen (see “Channel Pan” on page 39). So, if you, for example, set the Pan value in the Preset Select screen to 64L and set this Pan value to 63R, the actual pan amount would be 0 as these two pan parameters are relative to each other.

Halo Operation Manual 141 Preset Edit Menu Volume Envelope

Volume Envelope An envelope can be described as a “contour” which is used to shape the sound over time. The Volume Envelope controls the volume of the sound in the current layer over time. The way the volume of a sound evolves has a profound effect on how we perceive the sound.

Delay values below zero are Tempo-based values, meaning the time is based on the Master Tempo setting. Note values are displayed by adjusting the Delay Time value below zero. The sound will be delayed by the selected note value based on the master clock.

144 ENSONIQ Preset Edit Menu Non-Transpose Mode

Non-Transpose This function turns keyboard transposition On or Off for the current layer. Mode With Nontranspose “on,” the keyboard will not control the pitch of the instrument. This is a useful function for drones, attack “chiffs,” or other sound effects which you may not want to track the keyboard.

Fingered Glide: Same as Synth (last), except that Glide is disabled when playing Staccato, enabled when playing Legato.

Assign Group Use the Assign Group parameter to assign a certain number of channels to each layer. By assigning all voices in the preset to assign groups, important parts are protected from being “stolen” by more recently played keys. Or you can assign a voice, such as an open high hat, to a mono channel so it is cancelled by a closed high hat on the same mono channel. Layers rotate within their assigned “bin” of channels, not interfering with other bins.

L1 ASSIGN GROUP poly all

The modes are:

Poly All: Notes are played polyphonically with dynamic channel assignment using all 64 channels.

Poly 16 A-B: Two bins of 16 channels each. Notes are played polyphonically with dynamic channel assignment using no more than 16 channels.

Poly 8 A-D: Four bins of 8 channels each. Notes are played polyphonically with dynamic channel assignment using no more than 8 channels each.

Poly 4 A-D: Four bins of 4 channels each. Notes are played polyphonically with dynamic channel assignment using no more than 4 channels each.

146 ENSONIQ Preset Edit Menu Glide

Glide Glide creates a smooth transition from one note to the next instead of the normal instantaneous change in pitch when a new key is pressed. This effect is commonly heard on slide guitars, synthesizers and violins.

L1 GLIDE RATE CURVE 0.000 sec/oct linear

The front panel Glide Button LED comes on when the any layer of the current preset has a glide rate greater than 0.000 seconds (regardless of if a PatchCord is connected or not). Pressing the button turns the LED and glide off. Pressing the front panel glide button when all layers are set to a glide of 0.000 turns glide on with a rate of 0.142 seconds/octave.

The Glide Rate parameter deﬁnes the time it takes to glide to the new pitch (the larger the value, the slower the glide rate) The glide rate value range is from 0 through 32.738 seconds (zero means off).

The Glide Curve describes how the glide accelerates as it slides between notes. Because of the ear’s non-linear response to pitch, a linear glide sounds slow at the beginning and speeds up toward the end. Exponential curves actually sound smoother and more linear. Eight exponential curves are provided. Choose one that suits your style.

Glide can be either polyphonic or monophonic depending of the state of Solo Mode.

To Set up a Glide Rate Knob: 1. Set at least one layer to the minimum setting of 0.002 sec/oct. (This forces the Glide LED to come on.) 2. Connect the MIDI controller of your choice to Glide Rate on the layers you’d like to glide. Adjust the Cord Amount for the desired range. 3.

Halo Operation Manual 147 Preset Edit Menu Z-Plane Filters

Z-Plane Filters A filter is a device which changes the output of a signal (sound) by removing certain elements of the signal based on the frequency and amplitude. The “Order” of a filter defines the number of filter elements it contains. The more elements, the more complex the filter. Halo contains 50 different types of E-MU’s celebrated Z-plane filters. In addition to the standard Low pass, High pass and Band pass filters, Halo contains Swept Octave Equalizers, Phasers, Flangers, Vocal Formant Filters, and digital models of classic synthesizer filters. In the filter chart below you will notice that the “Order” of the filters varies from 2 to 12 order. Higher order filters have more sections and can produce more complex formants. Halo can produce 128 filters of up to 6th order or 64 filters of 12th order complexity. Therefore, if you decided to use all 12th order filters, Halo would be limited to 64 voices.

150 ENSONIQ Preset Edit Menu Filter Envelope

Filter Envelope The Filter Envelope is normally used to control the filter frequency and has six stages. Unlike the Volume Envelope, the Filter Envelope must be patched to the Filter Frequency using a PatchCord. In this respect, it can be thought of as a general purpose envelope generator which is normally patched to control the filter. The Filter Envelope Levels can be negative as well as positive. There are three mode options: • Time-based: Defines the Filter Envelope rates from 0 to 127 (approximately 1 ms to 160 seconds). The Master clock has no affect on time- based rates.

L1 FILT ENV RATE LEVEL Attack 1 84 100%

• Tempo-based: The Filter Envelope times vary based on the master tempo setting and are displayed in values such as 1, 2, 3, etc. Note values are displayed instead of a number when the time corresponds to an exact note value. Tempo-based envelopes are useful when using arpeggiators and sequencers because the envelope rates compress and expand according to the Master Tempo setting, keeping the envelopes in sync with the music. See the illustration on page 104.

L1 FILT ENV RATE LEVEL Attack 1 1/4 100%

• Envelope Repeat: The Envelope Generators can also be made to repeat. When the envelope repeat function is On, the Attack (1&2) and Decay (1&2) stages will continue to repeat as long as the key is held. As soon as the key is released, the envelope continues through its normal Release stages (1 & 2). For more information see page 104.

To Turn on Envelope Repeat: 1. Move the cursor until it is underneath the Mode ﬁeld as shown below.

The Basics section of this manual for Envelope has six stages to the contour: Attack 1, Attack 2, Decay 1, Decay 2, detailed information about how Release 1 and Release 2. When a key is pressed, the Envelope goes through the Envelopes work. the first four stages. If the key continues to be held, the envelope holds at the Decay 2 level. When the key is released, the envelope immediately jumps to the Release 1 stage, then the Release 2 stage finally ending at the Release 2 level.  The default PatchCord settings connect the Filter Envelope to Filter Frequency but +100 Sustain the envelope can be routed to Atk2 Dcy1 any real-time control destination using a PatchCord.

152 ENSONIQ Preset Edit Menu Low Frequency Oscillators (LFOs)

Low Frequency A Low Frequency Oscillator or LFO, is simply a wave that repeats at a slow Oscillators (LFOs) speed. Halo has two LFOs per layer identiﬁed on the display as LFO1 and LFO2.

An LFO can be routed to any real-time control destination using a PatchCord. LFOs have a myriad of uses, some of which probably haven’t been thought of yet. The following examples show a few common uses. • Control the pitch of the sound (LFO -> Pitch). This effect is called “vibrato” and is an important performance tool. Many presets use this routing with the modulation wheel controlling “how much” modulation is applied. • Create a “tremolo” effect by routing the LFO to control the volume (LFO -> AmpVolume). • Add a bit of animation to the sound by routing the LFO to control the ﬁlter. Set the PatchCord amount low for a subtle effect.

The LFOs have ﬁve parameters: Shape, Sync, Rate, Delay and Variation.

Shape LFO waveforms have different shapes. The shape of the waveform determines the effect of the LFO. LFOs have traditionally been used to add vibrato or repeating movement to a sound. These new shapes offer a lot of new programming possibilities.

L1 LFO1 SHAPE SYNC sawtooth key sync

If you modulate the pitch of an instrument, it’s easy to visualize the shape of the waveform. For example, the sine wave has a smooth, rolling shape that changes the pitch smoothly. The square waveform changes between two pitches abruptly. A sawtooth waveform increases the pitch smoothly, then abruptly changes back down. The available waveforms are shown below.

Sync The Sync ﬁeld speciﬁes whether the LFO is synchronized to a key stroke or is Free Running. Key Sync starts the LFO wave at the beginning of its cycle each time you press a key on the controller. In Free Run mode, the LFO wave begins at a random point in its cycle each time you press a key on the LFO Synced to 1/4 Note Clock controller.

Rate The Rate ﬁeld determines the LFO speed in absolute frequency rate values or tempo-based note values. All values equal to or greater than zero specify absolute frequency values from 0.08 Hz to 18.14 Hz.

154 ENSONIQ Preset Edit Menu Low Frequency Oscillators (LFOs)

Values less than zero specify tempo-based rates. If you modulate the rate of a tempo-based LFO, the rates will jump between the tempo-based note values with each PatchCord increment of “1”. As an example: if the LFO rate was set to 8/1 and you patched the Mod Wheel to control rate with a PatchCord amount of +1, turning the Mod Wheel to maximum would change the LFO rate to 4/1d. Refer to the chart below.

Halo Operation Manual 155 Preset Edit Menu Low Frequency Oscillators (LFOs)

Delay The Delay parameter deﬁnes the amount of time between hitting a key on the controller and the onset of the LFO modulation. Delay can be used to simulate an effect often used by acoustic instrument players where the vibrato is brought in only after the initial note pitch is established. The following illustration demonstrates how delay works.

time

Delay

key down

All Delay values equal to or greater than zero specify absolute time rates from 0 to 127. Values less than zero specify Tempo-based mode. Refer to the previous table for times and tempo-based rates.

Variation LFO Variation sets the amount of random variation of the LFO each time you press a key on the controller. This creates a chorus or ensemble effect since each note played has a slightly different modulation rate. The higher the value entered, the greater the note to note variation in the LFO.

The Variation value range is from 0 through 100. _ Variation is disabled when a Tempo-Based LFO is selected.

LFO variation changes the rate of each note to create an “ensemble” effect.

156 ENSONIQ Preset Edit Menu PatchCords

PatchCords PatchCords tie everything together by connecting modulation sources to destinations. Each PatchCord has its own Amount control which can be positive or negative (negative amounts invert the signal). In addition, the PatchCord amounts themselves can be controlled by any modulation source. Halo provides 24 patches for each layer.

There are three permanently connected control routings: volume envelope to ampliﬁer, pitch wheel to pitch and key to pitch. All other connections must be made using the PatchCords.

Modulation Amount +/- Source Destination

Each patch has an amount ﬁeld which determines how much modulation is applied to the destination. The modulation amount can be positive or negative. Negative values invert the input. The amount value range is from -100 to +100.

± centers around Zero. (Use for LFOs, Filt. Freq.) ± -630 +64

< modulation SUBTRACTS from the initial value < -127-63 0

“+” Modulation: Uses only the positive half of the range, adding to the current value. For example, if the filter frequency were set to 100 and you patched Vel+ to the filter, the filter frequency would increase from 100 as velocity was applied.

“±” Modulation: Uses both sides (full) range and both adding and subtracting from the current value. For example, if the filter frequency were set to 100 and you patched Vel ± to the filter, the filter frequency would decrease from 100 with key velocities of 63 or less and increase from 100 with key velocities of 64 and above. Therefore with medium velocity, the Filter frequency is approximately where you set it at 100. An LFO ± works the same way; on the positive half of the cycle it increases the initial amount and on the negative half of the cycle it decreases the initial amount. With a ± modulation source, a value of 64 equals 0.

“<” Modulation: Uses only the negative half of the range, subtracting from the current value. For example, if the Ampliﬁer Volume were set to +3 dB and you patched Vel < to AmpVol, the volume would be at +3 dB only when maximum key velocity were applied. Lower key velocities would scale back the volume. In general, < modulation is the proper choice when modulating Volume.

Preset Patchcords Preset PatchCords give you real-time control of global parameters. The effect processors are a powerful synthesis tool and this feature lets you control and use them in exciting new ways. For example, you can dynamically adjust the effects mix during a sequence or live performance. There are many exciting performance possibilities using Preset PatchCords to control Arpeggiator parameters and Effects Sends. The front panel knobs 15 & 16 are usually connected to Arp parameters in factory presets marked “arp:” Be sure to try out these controls There are 12 Preset PatchCords per preset with a source, a destination and an amount control. The amount can be set from -100 to +100. The Preset PatchCord controls are added to the FX Send Amounts set in the Global or Preset Edit menus. In other words, multiple sources connected to destinations are summed. O To crossfade between effects. PRESET CORDS #01 1) Set FXA Send 1 to 100%. 2) Set FXB Send 1 to 0%.

Initial Controller This parameter sets the initial value of MIDI controllers A-P when the preset Amount is ﬁrst selected. The front panel Control Knobs can be thought of as front panel MIDI controllers because in the Halo, they are treated just as if they originated from an external MIDI device. Refer to the following diagram. There are 4 Initial Controller Amount screens (A-D, E-H, I-L, M-P).

External MIDI controller numbers are assigned to the Letters A-P in the MIDI menu. The Initial Controller Amount value is sent to the PatchCord destination when the Preset is ﬁrst selected. If you move the Control Knob, then that value replaces the initial value. If MIDI controller data is received it will similarly replace the knob or initial setting.

INITIAL CONTROLLER AMT A:017 B:112 C:127 D: off

The Initial controller amounts can be set from 000-127 or they can be turned Off. If set to Off, the current controller value is used when the preset is ﬁrst selected. Setting the Initial Amount to “off” uses the values from the previously selected preset.

Halo Operation Manual 167 Preset Edit Menu Keyboard Tuning

Keyboard Tuning In addition to the standard equally divided octave tuning, Halo contains twelve factory programmed tunings and 12 user-deﬁnable tunings. The Keyboard Tuning parameter selects which tuning is used by the current preset. The User Tuning tables are deﬁned in the Global menu.

The factory Keyboard Tuning tables are described in the following table.

Tuning Tables Description Equal Temperament Standard Western tuning (12 equally spaced notes per octave) Just C Just intonation. (Based on small interval ratios. Sweet and pure, non-beating intervals.) Vallotti Valotti & Young non-equal temperament. (Similar to 12 tone equal temperament. Each key has a different character for a given scale.) 19-Tone 19 tone equal temperament. (19 notes per octave. Difficult to play, but works well with a sequencer.) Gamelan 5 tone Slendro and 7 tone Pelog. (Javanese. Pelog are white keys, Slendro are black keys. Exotic tunings of Gamelan flavor. Just C2 Allows you to play the following chords in the key of C: C, E, F, G, A, B, C#m, D#m, Em, F#m, G#m, Am, Bm Just C-minor Allows you to play the following chords in the key of C: C, E, F, G, A, B, Em, Am, Bm, C#m, D#m, G#m Just C3 Allows you to play the following chords in the key of C: C, D, F, Bb, C#m, Dm, Em, F#m, G#m, Am Werkmeister III A “well” temperament developed in the 17th century. Although you can play in all keys, each key sounds slightly different. Kirnberger Another well temperament developed by Johann Philipp Kirnberger where no pitch is more than 12 cents off from equal temperament. Scarlatti A variant of Meantone tuning which was used from the 15th to 18th centuries. Repeating Octave Middle C octave is repeated up and down the keyboard. Link with a preset in equal temperament to form unusual inversion up and down the keyboard. User 1-12 Define your own tuning tables (Global menu).

Refer to “User Key Tuning” on page 92 in the Global Menu chapter for instructions on how to deﬁne your own Keyboard Tunings.

168 ENSONIQ Preset Edit Menu Keyboard Tuning

The Just C Tuning Tables Well Tempered and Just were standard keyboard tunings up until the 20th- century when the current “equal tempered” scale became prevalent. In an equal tempered scale, the octave is equally divided into 12 parts. In Just or Well Tempered scales, the 12 notes are separately tuned to produce pure chords. However, in Just tunings you are limited to playing certain chords and if you play the wrong chord it may sound very BAD!  Halo implements the Halo allows you to modulate between keys by providing you 12 user tuning MIDI Tuning Dump protocol tables. Tuning tables can be changed as you play using a program change which allows you to create (create several presets with the same sound and different tuning tables), by tuning tables on your personal MIDI SysEx command (using a programmable MIDI footswitch or other computer and download them device), or using a continuous controller (link 2 presets and crossfade via MIDI. There are several between them using a controller). computer applications available on the internet which let you The Just C2, Just C min, Just C3 Tuning Tables create and download tuning These new tuning tables take the concept of just intonation a step beyond tables via MIDI. previous products. Fully explaining the mysteries of just intonation is beyond the scope of this manual, but the subject is covered exhaustively in Hermann Helmholtz’s On the Sensations of Tone, available at most libraries and bookstores. The new tables are called Just C2, Just C3, and Just C Minor. Try playing in the key of C/Cm using each table. You’ll quickly discover both the wonders and the frustrations of just intonation! In Just C, for example, you’ll ﬁnd that the chords C, Em, F, G, and Am sound beautiful. If you hold one of these chords, you’ll hear no “beating”. After playing for a few minutes, switch back to Equal Temperament for a rude awakening! At this point you might wonder why anyone would use Equal Temper- ament to begin with. For the answer to that question, play a D, Dmi, or Bb chord!.The intervallic ratios that make the C & G chords sound so pure make the D chord sound horribly out of tune. That's why we had to include Just C3. In this tuning, D, Dmi and Bb sound in tune, but the G chord will sound wrong. Each of the 4 tables allows you to play a different group of common chords in just intonation. Sadly, there is no single 12 note tuning that will allow all of the common chords to be in tune, and of course that's why they invented the equal temperament tuning system that we use today.

Just C Play these chords: C, E, F, G, A, Cm, C#m, Em, F#m, Gm, Am Just C2 Play these chords: C, E, F, G, A, B, C#m, D#m, Em, G#m, Am, Bm Just C2 minor Play these chords: C, Db, D, Eb, G, Ab, Cm, Em, Fm, Gm Just C3 Play these chords: C, D, F, Bb, C#m, Dm, Em, F#m, G#m, Am

Halo Operation Manual 169 Preset Edit Menu Preset Links

Preset Links You can link presets to other presets to create layering or keyboard splits. The current preset can be linked with up to two other presets (Links 1 & 2). Each linked preset can be assigned to a speciﬁc range in order to create keyboard splits or can be assigned a velocity range to switch links according to key velocity. In addition, you can specify Volume, Pan, Transpose and Delay settings for each Link. The modulation parameters speciﬁed in each preset remain in effect for each preset in the link.

Links provide an easy way to create new sounds by combining the existing presets. Or, you can create your own custom stacked presets with up to 12 layers! We’re talking LARGE sounds here. Of course Links can also be used when you just want to stack up two sounds. As an example, let’s stack two presets to create a big sound. Start with a preset you like, then go into the Links screen and start scrolling through the preset list while you play to hear both presets together. When you ﬁnd a winner, simply Save the preset and you’re ﬁnished! • You can “Split” the keyboard up to 12 ways by using combinations of the Layers and Links. • By adjusting the Velocity for the link, you can bring in the link by playing hard. • Transposing the Link can radically change the sound. • The delay parameter lets you create surprise effects, echoes or cascades of sound as you continue to hold the keys.

This feature allows you to temporarily solo individual layers or listen to them in any combination. This screen differs from the other Preset Edit screens in that it is NOT saved with the preset. The values reset each time you exit the Preset Edit menu.

Solo is activated by setting any layer to On (On = the layer is being Soloed). Any layers set to On will play and any layers set to Off will be muted. If all layers are set to Off, then Solo mode ends and all layers play normally. When you exit the Preset Edit menu, all layers play normally.

Effects Halo has two stereo effects processors. When playing presets one at a time, the two processors can be programmed as part of the preset. When the Overview MIDI Mode is set to “multi,” the Halo uses a global effects assignment (Master Effects). The diagram below shows how the effects are integrated into the signal path using a parallel effects send/return model, similar to a mixing console.

FX Send Amount

Reverb, Delay Effect A

Preset Dry Signal Main Outs Sum

Effect B Chorus, Flange FX Send Amount

The Effects Sends On a mixing console you can control the amount of signal each channel Sends to the effect bus. This allows each channel to be placed in a slightly different “sonic space” which creates an airy, open sound.

Halo uses this basic concept, but works in a slightly different manner. There are four effects busses: Send1-Send4. Each preset or each MIDI channel (you determine which), can be directed to one of the four busses. Each effect processor has four Send Amounts which allow you to set the wet/dry mix on each of the four busses going into the effect. A setting of 0% is completely dry (no effect). A setting of 50% contains an equal mix of affected and normal (dry) signal.

Halo Operation Manual 173 Effects Effects Overview

Send 2 is also used to route sounds to the Sub 1 outputs on the back panel. When a plug is inserted into the associated Submix jack on the back panel, the Dry portion of the Send is disconnected from the effects processor and the Dry signal is routed directly to the output jack. The Arrow (->) in the display points to the actual output routing. The Dry Send is disconnected from the Effects Processors even if only one plug is inserted into a Submix pair. The Effects Send is programmed for each layer in the Preset Edit menu. These routings can be overruled in the Global menu Mix Output screen by changing the submix setting from “preset”, which uses the preset routing, to Send1-Send4. In the diagram below, MIDI channel 1 is programmed to obey the preset routing, which in this case is Send 1.

OUTPUT SECTION & EFFECTS PROCESSORS

FX Sends Hall 1

Ch 3 SEND 3 S E N D 3

Ch 16 SEND 4 S E N GLOBAL MENU D 4

Individual layers or entire MIDI channels can be routed to any of the four busses.

The four Effect Sends allow you to get the most out of the two effect processors. For example, with Effect B set to an echo algorithm, you could route one MIDI channel to Send 3 and set the effect amount to 80%. Another MIDI channel could be routed to Send 4 with an effect amount of only 5%. The Mix Output function is also useful when sequencing since it lets you route speciﬁc MIDI channels to speciﬁc Sub outputs (on the back panel) where there they can be processed with EQ or other outboard effects.

Effect Parameters “A” Effect types contain Reverb and Delay effects. “B” Effect types contain Chorus, Flange and Distortion effects. There are 44 “A” effects and 32 “B” effects. In addition to the effect type, there are user adjustable parameters for each effect. The “A” effects have programmable Decay and High Frequency Damping. The “B” effects have user programmable Feedback, LFO Rate, and Delay Time.

Halo Operation Manual 175 Effects Effect Types

Decay The Decay parameter is used when setting “A” type effects. Decay sets the length of time it takes an effect to fade out. When setting up reverb effects, Decay controls the room size and the reﬂectivity of the room. For larger room sizes and greater reﬂectivity, set the Decay value higher. When setting up delay effects, the Decay parameter controls how many echoes are produced or how long the echoes last. The greater the value, the more echoes and longer lengths of time.

The Decay value range is from 0 through 90.

High Frequency Damping The HF Damping parameter is used when setting “A” type effects. High Frequency energy tends to fade away first as a sound is dissipated in a room. the HF Damping parameter adjusts the amount of damping applied to the signal’s high frequency elements which, in turn, changes the characteristics of the room. Rooms with smooth, hard surfaces are more reflective and have less high frequency damping. Rooms filled with sound absorbing materials, such as curtains or people, have more high frequency damping.

The value range for High Frequency Damping is from 0 through 127.

Feedback The Feedback parameter is used when setting “B” type effects. The Chorus and Flange effects have a controllable feedback loop after the delay element. Feeding back a small amount of the signal intensiﬁes the effect by creating multiple cancellations or images. Higher feedback values increase the amount of the Feedback loop.

The Feedback value range is from 0 to 127.

LFO Rate The LFO Rate parameter is used when setting “B” type effects. Both Chorus and Flange effects use a Low Frequency Oscillator (LFO) to animate the effect. LFO applied to a chorus effect creates the slight changes necessary for a realistic choral effect. Applied to a ﬂanger effect, the LFO moves the comb ﬁlter notches and adds animation to the sound.

The LFO Rate value range is from 0 to 127.

Delay Flanging, chorus and echoes are all based on a delay line where the signal is delayed by some time period and then mixed back with the unaltered signal. This parameter speciﬁes the how much time passes before you hear the delayed signal. On some effects, this value cannot be changed. In this case, the ﬁeld contains a dash.

The Delay value range is from 0ms to 635ms.

Halo Operation Manual 183 Effects General Effect Descriptions

General Effect Descriptions

Reverb Reverberation is a simulation of a natural space such as a room or hall. The reverb algorithms in Halo simulate various halls, rooms and reverberation plates. In addition, there are several other reverb effects such as Gated Reverbs, Multi Tap (early reflections), Delay and Panning effects. There are two adjustable parameters on the reverb effects - Decay Time and High Frequency Damping. Decay time defines the time it takes for the reflected sound from the room to decay or die away. The diagram below shows a generalized reverberation envelope.

Pre Reflex Reverb

AMPLITUDE Delay Cluster

TIME Decay Time After an initial pre-delay period, the echoes from the closest walls or ceiling are heard. These first echoes, or the early reflection cluster, vary greatly depending on the type of room. Roughly 20 milliseconds after the early reflection cluster, the actual reverberation begins and decays according to the time set by the Decay Time parameter.

High frequency energy tends to fade away first as a sound is dissipated in a room. The High Frequency Damping parameter allows you adjust the amount of high frequency damping and thus change the characteristics of the room. Rooms with smooth, hard surfaces are more reflective and have less high frequency damping. Rooms filled with sound absorbing materials such as curtains or people have more high frequency damping.

General Descriptions of the Reverb Types

Room: Programs simulate small rooms with high frequency absorption caused by drapes and furniture. Plates: Simulates plate type reverbs with their tight, dense, early reflections and sharp reverb buildup. Hall: Presets recreate the open, spacious ambience of large concert halls. Gated Reverbs: Add ambience only while the original signal is still sounding. As soon as the signal falls below a threshold, reverb is cut off. Delay: Programs can be used to create echo and doubling effects. Multi Tap: Programs consist of the reflection cluster only without the reverb decay.

184 ENSONIQ Effects General Effect Descriptions

Chorus The function of a chorus device is to thicken the sound or to make one voice sound like many. This effect is usually created by mixing one or more delayed versions of the signal with the original. The delay times used are too short to be perceived as an echo, but long enough so that comb ﬁltering does not occur. In addition, the delay time is varied via a low frequency oscillator to simulate the random differences which occur when multiple instruments are playing together. A slight amount of feedback improves the effect by creating multiple images of the sound as it recirculates again and again. All the choruses are true stereo using two separate delay lines controlled by a single set of controls. The delay times are slightly different for each channel and the LFO phase is inverted on one channel to help contribute to the overall chorus effect. The LFO Rate and Depth settings are critical to achieving a realistic effect, with faster LFO rates generally requiring less LFO amount and vice-versa.

Doubling When a copy of a sound delayed by about 26 milliseconds is added back to the original, two audio images are perceived by your brain. When the delayed image is slightly varied or modulated, the illusion of two voices is created.

Slapback Slapback is a single short echo in the range of 50-60 milliseconds. A sound delayed by this length of time is perceived as a discrete and separate image which is useful for a thickening effect or as a pre-delay for reverb simulating a hard, reﬂective surface such a gymnasium wall.

Stereo Flanger A flanger consists of a short audio delay line whose output is mixed together with the original signal. Mixing the delayed and original signals results in multiple frequency cancellations called a comb filter. Since the flanger is a type of filter, it works best with harmonically rich sounds.

This is the frequency response of a Comb Filter.

Flanging was originally created using two tape recorders playing identical recordings. By exactly synchronizing the two decks and then slowing the speed of one by grasping the tape reel ﬂanges, the ﬂanging effect was born.

Halo Operation Manual 185 Effects General Effect Descriptions

The Halo ﬂanger is a stereo device consisting of two separate delay lines controlled by a single set of controls. A Low Frequency Oscillator (LFO) varies this initial delay setting, changing the frequency of the notches and adding animation to the sound. LFO Rate controls the rate of change and LFO Depth controls how much the LFO changes the delay.

The Feedback control sends some of the delayed signal through the delay line again. When feedback is used the comb ﬁlter notches are deepened.

Delay Delay is an effect which can be used for doubling, reverb pre-delay, or echoes.

Delay Time is variable from 0-635 mS and controls the time between echoes. Feedback and determines how long the echoes continue sounding. “Inﬁnite” delay effects are also possible without the risk of runaway.

Stereo Delay Similar to delay except that the delay line outputs a stereo signal from the mono input. The two output signals are a few milliseconds apart to create a stereo image. The delay times are variable from 0-635 mS.

Panning Delay A panning delay is similar to the normal delay lines except that the echoes bounce back and forth between the two stereo speakers.

Dual Tap These are delay lines where the signal is “tapped off” at two unevenly spaced locations. When feedback is used, multiple complex echoes are produced. The fraction in some of the algorithm names (i.e. 1/3, 1/4) refers to the time ratio between the taps.

Vibrato Basically, this a delay line modulated by an LFO, but with none of the original signal added in. The LFO modulation creates a Doppler shift and a resultant cyclical pitch shift. The vibrato created in this manner sounds very different than vibrato created by frequency modulating the sample.

Distortion Distortion uses a technique called “soft-clipping” to create additional harmonics in the signal. As the level increases, the top of the waveform becomes somewhat squared. As the level increases further, it transforms into a true square wave.

Soft clipping gradually squares the edges of the waveform as the amplitude is increased.

186 ENSONIQ Save/Copy Menu

The Save/Copy button is used to save changes to a preset, copy data between presets, randomize presets and to move other types of data. The menu is context-sensitive and will start at the appropriate save screen. If multiple items need to be saved, then the screens have the following priority: pattern, song, preset.

There is so much you can do with the Halo it would be impossible to describe it all. This chapter is will give you a few ideas for programming your own custom sounds and contains step-by-step instructions to help you get started. In order to get the most from this chapter, we recommend you actually try each example.

Editing Presets One of the easiest ways to make a new preset is to edit an existing preset. This is also an excellent way of becoming familiar with Halo. If you don’t like what you hear, simply select a new preset, then Halo reverts to the original sound. Changes are not permanent until you Save them (see “Saving a Preset” on page 187). Let’s experiment and modify a few parameters of an existing preset. We’ll start with functions that have an obvious effect on the sound: Instrument Select, Tuning, and Chorus.

Changing the Changing the instrument is the easiest and most dramatic way to modify Instrument an existing preset. To Change the Instrument for the Current Layer: 1. Choose any cool preset, then press the Preset Edit button. 2. Press the #1 Jump button twice to jump directly to the Instrument page. See “Preset Menu Jump Keys” on page 36. O The Preset Edit Jump Buttons are located in the “Command Functions” section L1 INSTRUMENT ROM:HALO of the front panel. 0185 syn: Pad Synth

3. Move the cursor down to the bottom line (using a Cursor button). 4. Use the Channel button to turn select the various layers. Use the data entry control to turn OFF all layers except L1. This allows you to hear the different instruments by themselves. 5. Play the keyboard as you scroll through the various instruments.

Halo Operation Manual 197 Preset Programming Editing Presets

To Change the Instrument for any Layer in the Preset: 6. Use the Channel Select buttons to select another layer.

L2 INSTRUMENT ROM:HALO 0078 str:Pizz Strings

7. Find another instrument that sounds good when combined with the previous instrument selected. 8. Repeat steps 6 and 7 if you want to add additional layers (although two layers will be enough for these experiments). Now let’s play with the tuning.

Changing the Tuning Tuning the selected layer of the preset changes the pitch of the key on the of an Instrument controller. If the numbers are “00,” it means that the instruments are tuned to concert pitch (A=440 Hz). The Coarse tuning value represents whole semitone intervals. The Fine tuning value shifts the pitch in 1/64 semitones (or 1.56 cents).

To Tune the Instrument of the Current Layer: 1. Press the #3 Jump button twice to jump directly to Tuning page.

L1 TUNING Coarse: +36 Fine: +6

2. Move the cursor to the Coarse field (using the cursor button). 3. Set the value to +12 to shift the pitch up a whole octave. To shift the pitch in smaller units than a semitone, use the Fine field. Try tuning one of the instruments to a perfect fifth above the other by setting the Coarse value to +7. Tuning an instrument far out of its normal range completely changes the character of the sound. For example, if you tune a bass guitar up 2 octaves, it's going to sound rather petite. On the other hand, if you tune it down 2 octaves, you can probably rattle plaster off the walls! Experiment with radical pitch shifting. You'll be surprised at the results.

198 ENSONIQ Preset Programming Editing Presets

Chorus This is an easy one. Chorus works by doubling the instruments and detuning them slightly. The larger the chorus value, the more detuning occurs. The Width parameter controls the stereo spread. A Width value of 0% reduces the chorus to mono, a value of 100% provides the most stereo separation. Chorus is useful when you want to “fatten up” a part quickly and easily.

To Chorus a Layer: _ WARNING: Since it 1. Press the #5 Jump button to jump directly to the Chorus page. works by doubling the 2. Use the cursor buttons to advance the cursor to the Chorus field (the instruments, Chorusing halves first field in the bottom line of the display). Use the data entry control the number of notes you can to turn on chorus. play on Halo.

L1 CHORUS WIDTH off 100%

3. Select a Width value based on the amount of detuning you want. Smaller numbers mean less detuning, larger ones more. You can select various amounts of chorusing for each of the instruments, just play around with the Chorus and Width parameter until you like what you hear.

Volume Envelope Every sound you hear, whether it’s a piano note, a drum, or a bell, has a characteristic volume curve or envelope. This Volume Envelope shapes the volume of the sound which grows louder or softer in various ways during the course of the sound. The volume envelope of a sound is one of the clues our brain uses to determine what type of sound is being produced. An envelope shapes the sound or volume of the sound over time. The envelope generators in Halo all have six stages to the contour: Attack 1, Attack 2, Decay 1, Decay 2, Release 1 and Release 2. When you press a key on the keyboard, the envelope goes through each of the first four stages, advancing to the next stage when the defined Level for each is reached. As long as you continue to hold the key down, the envelope continues through the first four stages holding at the end of the Decay 2 level until the key is released. When you release the key, the envelope jumps to the Release stages (no matter where the envelope is when you release the key) ending at the Release 2 level.

Every instrument in Halo has it's own predetermined volume envelope which is used when the Volume Envelope parameter is set to “factory.” By setting the Volume Envelope to “time-based” or “tempo-based,” we can Strings reshape the instrument's natural volume envelope any way we want. By reshaping the volume envelope of a instrument, you can dramatically change the way the sound is perceived. For example, you can make “bowed” pianos or backward gongs. The diagrams to the left show the characteristic volume envelopes of a few common sounds.

Percussion In preparation for this experiment choose almost any of the standard organ presets which sustain as long as the key is held down. Go to the Instrument page and set it to “None” on all layers except Layer 1. Now you’re ready to play with the Volume Envelope.

Adjusting the Volume Envelope (the easy way): Many sounds don’t require a complex six-segment envelope. Over the years, a simpler Attack-Decay-Sustain-Release envelope, or ADSR, have become standard. The front panel controller knobs on Halo have been preprogrammed to adjust these four volume envelope parameters. A diagram of this standard ADSR envelope is shown below.

1. Front panel knobs E-H are routed to the volume envelope parameters. This is the easiest way to change the volume envelope settings. 2. Press the front panel Controller button E-H to select: Amp Attack, Amp Decay, Amp Sustain, Amp Release.

200 ENSONIQ Preset Programming Editing Presets

3. Increase the Amp Attack knob and play a note. The attack controls the time it takes for the sound to reach the Attack level when a key is pressed and held. 4. Increase the Amp Release knob. Note the effect as you release the key. The Release stages controls the time it takes for the sound to die away when a note is released. 5. Try out the Sustain & Release knobs. The Sustain knob control the volume LEVEL after the Decay phase has ﬁnished and while the key continues to be held. As soon as you release the key, the Release phase begins.

To Create a Complex Volume Envelope: 1. Go to the Volume Envelope mode screen, by pressing the “Amp” jump button twice, and set the Volume Envelope mode to “time-based.”

Note the effect as you release the key on the controller. The Release stages controls the time it takes for the sound to die away when a note is released.

To Setup the Volume Envelope as an ADSR: The classic synthesizer ADSR (Attack-Decay-Sustain-Release) envelope is easy to create using the Halo six segment envelope generators. The trick is to only use segments: Attack1, Decay2, and Release1.

Working with Filters The filters make it possible to remove certain components of the sound. A low pass filter removes the high frequency components or put another way, it “lets the low frequencies pass.” A high-pass filter removes the low frequency components from the sound letting only the high frequencies pass. See “Halo Filter Types” on page 148 for a complete list of Halo’s filters and their descriptions. In preparation for the next tutorial, set up the Halo with a single instrument layer on Layer 1.

1. Go to the Instrument screen (Preset Edit menu) and select Instrument #140 - wav:Sawtooth 1. This is a harmonically rich sound. Since ﬁlters work by removing or accentuating certain frequencies, we want to make sure that we have a lot of frequencies to start with. 1. Advance to the Filter Type screen using the data entry control. Select the Classic 4th order ﬁlter.

If you play the keyboard now, you should hear the raw sound. Slowly decrease the filter cutoff frequency value as you play the keyboard. The sound

202 ENSONIQ Preset Programming Editing Presets

gets more and more dull as you remove more and more high frequencies from the sound. At some point, the sound completely disappears. (You have ﬁltered out everything.) The chart on the following page illustrates what you just did.

100 Cutoff Frequency

80 Output of Filter

40 Amplitude 20

40 80 160 360 720 14402880... Frequency

3. Turn the ﬁlter back up to full, then adjust the Q. 4. Set the Q about halfway up, then adjust the Cutoff as you play the keyboard. As you change the Cutoff, notice that the sound now has a sharp, nasal quality. A high Q boosts or ampliﬁes the frequencies at the cutoff frequency (Fc).

Adding the Filter Envelope Now let's modulate the Filter Frequency with the Filter Envelope. The Filter Envelope is a device that can automatically change the ﬁlter frequency during the course of the note. Before we deﬁne the Filter Envelope, we need to patch the Filter Envelope to the Filter Frequency.

To Setup the Filter Envelope: 1. Go to the PatchCord screen by pressing the Cords Jump Key.

L1 PATCHCORD #03 FiltEnv+ -> FiltFreq +100

2. Move the cursor to PatchCord #3. This patchcord is preprogrammed to connect the Filter Envelope to Filter Cutoff Frequency. 3. Move the cursor to the last field in the lower line. This is the Amount field. The Amount field determines the amount of modulation applied. Set this value to +100.

9. Change the attack rate and note the change in the sound. 10. Set the envelope parameters as shown in the following table.

Envelope Phase Time Level % Attack 1 40 65 Attack 2 65 100 Decay 1 80 85 Decay 2 25 50 Release 1 97 20 Release 2 73 0

With the above setup, the ﬁlter sweeps up, then Decays back down to the Decay 2 Level until you release the key. Then it sweeps down at the Release rates. Play with the envelope parameters for awhile to get a feel for their function. (If you're having trouble understanding the Envelope Generators, please refer to the Programming Basics section in this manual.)

Changing Filter Types Go back to the Filter Type screen shown below and move the cursor down the lower line of the display. Change the ﬁlter type while playing the keyboard. There are 50 different ﬁlter types.

L1 FILTER Ord Type Aah-Ay-Eeh 6 VOW

These filters are extremely powerful and have been carefully crafted to offer maximum flexibility and musical control. You may want to change the Envelope (PatchCord) Amount, Q and/or the Filter Frequency to get the right sound for each filter and instrument. These three controls, coupled with the Filter Envelope, are perhaps the most important controls on any synthesizer. Take the time to learn how they interact with each other and you will be able to create sounds beyond imagination.

Halo Operation Manual 205 Preset Programming Editing Presets

Envelope Repeat The Envelope Generator can also be made to repeat. When the envelope repeat function is On, the Attack (1&2) and Decay (1&2) stages will continue to repeat as long as the key is held.

To Make the Filter Envelope Repeat: 1. Go to the Filter Envelope Mode screen shown below. 2. Move the cursor to the Mode ﬁeld.

L1 FILTER ENVELOPE Mode: time-based

3. Turn the data entry control clockwise. The Mode ﬁeld will change to Repeat as shown below.

L1 FILTER ENVELOPE Repeat: on

4. Move the cursor to the on/off ﬁeld and turn Envelope Repeat On. 5. Play a key on the keyboard. You should now hear the envelope repeating. 6. Go back to the envelope parameter page and adjust the Attack 1&2, and Decay 1&2 parameters. The repeating envelope cycles through these four stages as long as the key is held.

Practice Modulating • Try modulating the pitch with the Filter Envelope generator. • Use Velocity to modulate the Filter Envelope PatchCord or the Filter Frequency. This brightens the sound as you play harder. • Program the LFO to modulate Filter Frequency and Volume (Patch- Cord screen). • Modulate the LFO with the other LFO, with Velocity, and with the Pitch Wheel. • Examine the Factory presets to learn how they’re constructed. There are lots of cool synthesis tricks you can use in your own presets. • We’ve programmed the front panel knobs our way, but since they’re completely programmable there’s no reason why you can’t create your own custom controls. • Think of ten exotic modulation routings, then try them out. Experimentation is the key to learning how to control Halo.

206 ENSONIQ Preset Programming Editing Presets

Troubleshooting A common source of confusion when working with the filter envelope is that the Attack or Release parameters might not seem to be working correctly. If you are not getting the expected result, try to analyze the situation. There will be many times when you will have to stop for a minute and think, “What am I trying to do and why isn't it working?” When this happens (and it will), don't panic. Troubleshooting is a normal part of the synthesis process. Simply examine the various parameters and try to be as analytical as possible as you solve the problem. The solution is usually simple. (“The filter is already wide open and can't open any more.” or “Another PatchCord is connecting something to the parameter and affecting it.”) Learning to play any instrument takes a little patience and practice. Referring to the diagram below which shows the Halo signal flow, notice that the DCA comes after the Filter. The DCA controls the final volume of the sound, so if the filter's release is longer than the release for the DCA, you won't hear it, because the DCA has already shut off the sound.

Halo Operation Manual 231 Appendix Installing Sound SIMMs

Installing Halo can be easily expanded to contain up to 128 MB of sound data Sound SIMMs (4 SIMMs).

Remove the ROM Hatch Cover: 1. The sound SIMM sockets in Halo are located beneath a small hatch on the bottom panel. Unplug power from the unit and carefully turn it keyboard-side down on a soft, padded surface. 2. The ROM hatch is a 125cm x 140cm rectangle secured by four screws. (You can’t miss it.) Remove the four phillips head screws securing this hatch and place them and the hatch cover where they won’t get lost.

To Remove ROM SIMMs (if necessary): 1. Orient the unit so that the rear panel is facing you. Ground yourself by touching a grounded object. (Such as the chassis of another piece of equipment connected to the wall socket with a three-prong power plug.) 2. On each end of the SIMM socket there is a silver or plastic tab. Use a screwdriver or a ball point pen to squeeze the tabs toward the outside of the socket while gently nudging the SIMM toward the right side of the unit. The old SIMM should “hinge” to the right and can now be removed.

1. Set SIMM into socket with the notch toward back rear of unit of unit.

232 ENSONIQ Appendix Installing Sound SIMMs

Install a New ROM SIMM 1. Ground yourself by touching a grounded object, then remove the memory SIMM modules from the static protected packaging. 2. Notice that one end of the SIMM connector is notched. This notch Install the SIMM closest to the LEFT side ﬁrst. (When the rear of the unit is closest to you.) 3. Gently set the SIMM deep into the SIMM socket at a 45º angle with the notch toward the keyboard. Without forcing the insertion, let the board rest in the socket as deep as it will go. It should rest naturally in place at this 45° angle. See the following diagrams. 4. While applying a slight downward pressure on the top of the SIMM to keep it from popping out of the socket, tilt the SIMM board into a vertical position. You should hear an audible click. Make sure both sides of the silver tabs have latched.

Reassemble the Unit 5. Replace the hatch cover and the four screws. The screws are all identical.

Test It The installation is almost ﬁnished. 1. Turn the unit right-side up and plug in the power cord. 2. Turn on power. 3. Place the cursor under the ROM ﬁeld of the Main screen and turn the data entry control to verify that the new sound ROM has been recognized. 4. Play the presets on the new ROM banks and verify that they sound OK.

Problems? 1. Disconnect power immediately. 2. Open the unit, and try re-seating the ROM SIMMs. Take care that the RAM SIMMs are properly installed in the sockets. If you’re still having problems, return the unit to its original conﬁguration and call EMU / ENSONIQ Customer Service at (831) 438-1921. Telephone support hours are 8:00-5:00 PST, Monday through Friday.
